Black Hole, Small

At TinySci, it’s only natural for us to get excited about all things small, even if it means, relatively small. In this case, Nikolai Shaposhnikov and and Lev Titarchuk of NASA’s Goddard Space Flight Center announced the tiniest black hole ever discovered, one weighing in at only 3.8 solar masses. If you were wondering, that translates to approximately 7.6E+30 kilograms, or about 1,270,000 Earths.

I know what you’re thinking: It doesn’t sound quite that small, right?

But compared to the supermassive black hole residing in the center of our galaxy, it would take about 684,000 of these small black holes to pack the same punch as as ours. Plus, a quick and dirty calculation of the event horizon radius (R = 2GM/c2) puts it at approximately 7 miles from the center of the black hole. Which implies, if you were were so daring, you could get awfully close without getting pulled in, though I’m not sure how you’d fare against the barrage of high-energy x-rays.
